CUTTING MEANS FOR CENNING APPARATUS.

Specification of Letters Patent.

Patented Jan. 1 Q, 1915..

Application filed December 13, 1913. Serial No. 806,455.

1 b all who/rt it may concern:

Be it known that we, JAMES SCHLOTHAN and ll lnmmr F. Scum/THAN, citizens of the United States, and residents, respectively, of the city and county of Sen Francisco, State of California, and the city of Ketchiken, Territory of Alaska, have invented certain new and useful Improvements in Cutting Means for Canning A paratus, of which the following is a speciiihation.

The invention relates to canning apparatus and particularly to an apparatus for cutting and. inserting into the can food products, such as fish.

The object of the invention. is to provide an improved cutter for cutting .the food product into cylinders, preparatory to inserting it into the can.

Anotherobject of the invention is to provide means for removing the shreds of fish meet from the cutters at each cutting operation.

The invention possesses other advanta genus features. which, with the foregoing, will be set' form at length in, the following description, where We shall. outline in full that form of our invention 'which we have selected for illustration in the drawings occompanying and forming part of the present specification. The novelty of the invention will be included inthe claims succeeding said description. From this it will be apparent that we do not limit ourselves to the showing made by said drawings and description as we may adopt many variations Within the scope of our invention as set forth in said claims.

Referring to said drawings: Figure 1 is a sectional elevation of a portion of a canning machine including the devices of our invention. Fig. 2 is a vertical. section of a fragment of the machine on a larger scale. Fig. 3 is a section taken on the line A-A Fig. 1. .Fig. 4 is an elevation of the knife alining and driving means.

The general const uction of the machine, such as the frame and driving means, are well known to persons familiar with the art and Will not be described orillustrated herein. The function of the machine is to out the food product into the desired shape and insert it into the can, and machines of this general character are employed in the selcan feeding apparatus.

'outer knife is beveled at mon canning industry for cutting the fish meat into cylindrical shapes, corresponding in size to the size of the can. The fish are cleaned and boned and formed into cake, either cooked or raw, and the portions to be inserted into the separate cans are cut from the cake.

The cake is fed alon' a table 2 above which is arranged the cutting apparatus and below which are arranged the cans and the The table is provided with an aperture 3 nlinedwith the. cutter and the can, through which the cut portion of fish meat passes into the can Arranged below the table 2 is a turret l: which is given a step by step movement by any suitable means, such. as the spider 5 secured to the turret shaft 6 and the revolving arm 7, fixed to the shaft 8, which is rotated at theproper speed by any suitable mechanism. The turret +l conveys the empty cans into alinement with thcaperture and they :ire then moved into Contact with the lower surface of the table by the plunger 9, which is vertically reciprocated by some suitable means, such the cam 12., loosely mounted on the shaft 6. lhe cam is rotated by shaft 8 through the gears 13 and. 1-4;, the gear 1- 1 being attached to the cam. lifter the can has been filled, the plunger 9 moves downwardly, the can is again seated in the turret, which revolves and removes the filled can end places another empty one in position.

Arranged above and alined with the aperture 3 is the cutter. llhe cutter consists of two cylindrical lrnives 15 and 16 arranged concentrically and contiguous. lhe lower or cutting edges of the knives lie in the some plane and are provided with sharpened teeth 17. The lower edge of the inner knife 15 beveled or chemfered on its outer sur face and the lower edge of the outer knife 16 is beveled or inclined,-so thet the inner surface thereof contacts with the bevel on the outer surface of the inner knife. The outer surface of the inclined portion of the a greater angle than the inner surface in order to produce a. sharp cutting edge. By this arrangement the outer knifelfi cannot move vertically upward with respect to the inner knife the inner knife cannot move vertically downivieens kDITES in opposite ciirections, so that the teeth hereon slicer the fish meet as the r1 i L are provulmi 10E row/mg, we

The frame has a cross arm e3" through which extend shafts 4-0 and 41, said shafts being journuled in said arm. shafts areseourecl the gears 19 and. 22 re speciiveiy. Collars 112 and 13 are secured on said. shafts which engage the upper and lower sides of the arm 23" to cause the slmtfi's to more up see down with the frame so to iris-stain the gears 19 and 22 in slice the gears L8 and 21 respectively 5 4:0 and are rcspectiveiy siiriebiy jourimlei in bearings and 4:6 which besriugs We secured to fixed supports 41?, A pulley i slidebly mounted on shaii; l0 iyeiweeu the end members of bearing one. pulleys and 50 are sliciobly mounted on chefs e1 between the end members of the beefing 16- so that said pulleys do not more iorigicuriimiiiy with said. shafts, The puiieys ere "feathered to saiol shafts so that they rotate therewith.
